Image lookups with bad locality is exactly what a GPU's texture pipeline is for
- amelius 4y agoHow does this pipeline deal with the locality issue, assuming the texture doesn't fit in the cache?
- WithinReason 4y agoThe texture cache tries to guarantee that every pixel is only read from DRAM once, and the texture sampler does bilinear sampling "for free". So a sequential copy and a "rotation copy" should take about the same time.
